If the vehicle has been driven, let it sit for 20-30 minutes before draining the oil.
How long can an engine run without oil?
The presence of oil and its distribution is absolutely crucial to an engines continued operation. Engines can work without oil, but the effect is so damaging they are only capable of running for less than 30 minutes until failing – and in most cases, it’s a lot quicker than that.
